Electrical outlet

An electric power supply port comprising:

• i) a first electrical outlet (1) comprising:
• first electrical contacts in turn comprising a first phase (11) and a first neutral (12);
• a first group of holes in turn comprising at least a first and a second hole (13, 14), one associated with the first phase (11) and one associated with the first neutral (12) and intended to allow an insertion of corresponding pins of an external electric plug;
• ii) a second electrical outlet (2) side by side with the first electrical outlet (1);
• the second electrical outlet (2) comprising:
• second electrical contacts in turn comprising a second phase (21) and a second neutral (22);
• a second group of holes in turn comprising at least a third and a fourth hole (23, 24), one associated with the second phase (21) and one associated with the second neutral (22) and intended to allow an insertion of the corresponding pins of the external electric plug;
• the first, second, third and fourth hole (13, 14, 23, 24) are aligned according to this order along the same straight line;
• a distance between a geometric centre of gravity of an inlet mouth of the first hole (13) and a geometric centre of gravity of an inlet mouth of the second hole (14) is the same as a distance between the geometric centre of gravity of the inlet mouth of the second hole (14) and a geometric centre of gravity of an inlet mouth of the third hole (23) and is the same as a distance between the geometric centre of gravity of the inlet mouth of the third hole (23) and a geometric centre of gravity of an inlet mouth of the fourth hole (24);
• between one of the holes of the first group associated with the first phase (11) and one of the holes of the second group associated with the second phase (21), there being one of the holes of the first group associated with the first neutral (12) or one of the holes of the second group associated with the second neutral (22).
